I, personally, agree entirely. They need to release at least one major new IP every year for the WiiU (actually, if they did one casual + one 'hardcore', that'd be the sweet spot), and also start being more creative with the ones they have. They've been playing it too "safe" with their current IPs - Mario especially.
I do also think that more advertising would make a world of a difference for the system's popularity, but word of mouth can do the trick if they put out good enough games.
